Northrop Grumman Systems Corp, Aerospace Systems, has been awarded a a multi-year, fixed-price-incentive-firm target contract valued at more than $3.6 billion by the U.S. Navy to deliver 25 new E-2D Advanced Hawkeye aircrafts.

“The E-2D Advanced Hawkeye is the Navy’s primary airborne early warning and battle management command and control platform,” said Navy Capt. John S. Lemmon, program manager, E-2/C-2 Airborne Tactical Data System Program Office, in a release.

Developed and produced by Northrop Grumman, the E-2D Advanced Hawkeye is the world’s only aircraft specifically designed as a carrier-based airborne early warning and control (AEW&C) system. With its structurally distinctive design – a rotating rotodome and four vertical stabilizer tail configuration – the E-2D Advanced Hawkeye provides unprecedented, 360-degree surveillance to the warfighter.

The E-2D Advanced Hawkeye will see more powerful upgrades from its predecessors, like the AN/APY-9 radar system, which “allows the warfighter to ‘see’ a greater number of targets at much greater distances – as well as new avionics and a glass cockpit.”
